  Weird problem with transparent box

The attached image shows two renderings of the same scene.  The right image is
the same as the left, except that I added a completely transparent box, whose
purpose was to support media with some ground fog:

box {
   -size/2, size/2
   texture { pigment { color rgbt 1 } }
   translate <0, size.y/2, 0>

As you can see, the box shows up as a mirror instead of being transparent.

The scene is fairly complex, but here are a few details that might help point
out to the experts what the problem might be:

1.  The whole scene is inside of a mesh-based sky sphere, but I verified that
the problem shows up even if that is turned off.
2.  I have enabled radiosity, but I verified that the problem shows up without
it as well.
3.  The light source is a sun emulator using a parallel area_light at a far
distance from the scene

I also tried using rgbf 1.0 as the pigment for the box, but I get the same

Any ideas?  It's driving me crazy
